I accidentally wrote my homework with a ballpoint pen, but I was supposed to use a pencil. Do you have an eraser that can erase ballpoint pen writing?
Certainly. Please wait a moment.
Which eraser can remove ballpoint pen writing?
When you write with a ballpoint pen, the ink is absorbed into the paper.
Oh dear, that's not right.
I rubbed really hard, but it didn't disappear at all! All it did was crumple the paper.
The ink from a ballpoint pen absorbs into the paper, so it doesn't rub out with a regular eraser.
HintTo remove ink, you need to scrape off the surface of the paper as well.
Correct!
Sand erasers are specially made to remove ballpoint pens and printed text. They contain a fine abrasive called silica sand that removes text along with the surface of the paper. If you rub too hard, you'll tear the paper, so take it slow and rub gently.
Hello, how can I help?
Do you have an eraser that works well with dark pencil sketches?
Certainly. Please wait a moment.
Which eraser can effectively rub out sketches drawn with a dark pencil?
Drawing with a dark pencil leaves more graphite sheets on the paper.
Oh dear, that's not right.
Huh?! That didn't work, and it got the page all dirty!
Plastic erasersSand erasers are not well suited to dark pencil sketches, as they struggle to pick up all of the graphite sheets and may leave black stains on the paper.
Correct!
Kneaded erasers are soft and sticky, so they can easily remove dark pencil lines, make them lighter, or erase fine details with minimal pressure. They also don't leave eraser dust, so they're great for sketches.
